Struct Store 

pub struct Store<B> { /* private fields */ }

Node values under their keys. A render reads through it and spills what it computes to the staging area; only persist changes the store, committing each staged value whole by rename, least recently used going first past the budget.

Implementations

impl<B: Backend> Store<B>

pub async fn open(backend: B, max_bytes: u64) -> Result<Store<B>, String>

A store another version wrote is emptied first.

pub fn max_bytes(&self) -> u64

pub fn bytes(&self) -> u64

pub fn holds(&self, key: Hash) -> bool

pub async fn persist(&self) -> Result<Persisted, String>

A staged value whose meta was never staged is dropped. Each key leaves the staging record only once its files have, so a write that fails leaves every later one staged.
